StreamTokenizer

[sandeepmur]

Hi,

I have a text file with 2 lines:
client=24
clientname=dragon

I am trying to use a stream tokenizer to open and read the file but having some problems. my code is as follows:

StreamTokenizer tokenizer = new StreamTokenizer(new FileReader("res.txt&quot);
int nextTok = tokenizer.nextToken();
while (StreamTokenizer.TT_EOF != nextTok) {
if (StreamTokenizer.TT_NUMBER == tokenizer.ttype) {
out.println("It's a number!"
out.print (tokenizer.nval + " "
}
else if (StreamTokenizer.TT_WORD == tokenizer.ttype) {
out.print (tokenizer.sval + " "
}
}

Its taking an awfully long time to read the file. Is there a better way to read the text file?

I need the values 24 and dragon in 2 different strings.

appreciate any help..
thnx,
sg

	  	Properties aaa= new Properties();
	  	InputStream aaaStream = new FileInputStream("myfile.txt");
	  	aaa.load(aaaStream);
		String client= aaa.getProperty("client");
	    String clientname= aaa.getProperty("clientname");

Or you could use a BufferedReader and call the readLine() method, and then split the String using a StringTokenizer.

Hi, another small help. I am obtaining the path of the current directory as in:
String original = application.getRealPath(request.getServletPath());

which is returning "C:\Program Files\Apache Group\Tomcat 4.1\webapps\site\client1\file.jsp"

My objective is to obtain the name of the present directory which is "client1". any ideas?

thnx in adv

I'm sure there is a better way to do it, but as a simple hack :

StringTokenizer st = new StringTokenizer("C:\Program Files\Apache Group\Tomcat 4.1\webapps\site\client1\file.jsp", "\\");

int cnt = st.countTokens();
for (int i = 0; i < cnt -2; i++) {
   st.nextToken();
}

String currentDir = st.nextToken();
System.out.println(currentDir);

thnx a bunch!

You could also do something like this:

File curDir = new File( original );
String parentDir = curDir.getName();

The

File.getName()

method returns the last directory/file name in a path.

 

[sandeepmur]

File curDir = new File( original );
String parentDir = curDir.getName();

returns only the file name while all i want is the directory name.

thnx

Sorry, I didn't understand your question at first. Perhaps this will work:

File curDir = new File( original );
String parentPath = curDir.getParent();
File parentDir = new File( parentPath );
String parentDirName = parentDir.getName();

Seems like more code than necessary, though.
